ath9k: Postpone key cache entry deletion for TXQ frames reference it
commit ca2848022c12789685d3fab3227df02b863f9696 upstream.
Do not delete a key cache entry that is still being referenced by
pending frames in TXQs. This avoids reuse of the key cache entry while a
frame might still be transmitted using it.
To avoid having to do any additional operations during the main TX path
operations, track pending key cache entries in a new bitmap and check
whether any pending entries can be deleted before every new key
add/remove operation. Also clear any remaining entries when stopping the
interface.
